Key Storylines

Swiatek returns to action: The World No.1 is set to play her first tournament since winning her first US Open title and seventh title of the season. 

Race to the WTA Finals heats up: More than any other segment of the season, points are at a premium over the next three weeks, where one match could decide a player's postseason fate. Just ask Ons Jabeur and Anett Kontaveit. The Estonian was ranked No.30 when she marched to the Ostrava title last year and ultimately overtook Jabeur to finish in the Top 8 and qualify. 

Players in Race positions 10-20 in Ostrava: 

Maria Sakkari (Race No.10)
Paula Badosa (Race No.11)
Madison Keys (Race No.12)
Belinda Bencic (Race. 13)
Beatriz Haddad Maia (Race No.14)
Anett Kontaveit (Race No.17)
Jelena Ostapenko (Race No.18)
Ekaterina Alexandrova (Race No.20)

Kasatkina looks to shore up qualifying chances: Along with Swiatek, Kasatkina is the only other player in the Top 8 of the Race playing this week. A champion in San Jose and Granby this summer, Kasatkina sits at No.7 in the Race and is just over 100 points behind Coco Gauff at No.4. 

Alexandrova, Ostapenko, Raducanu building on Seoul: All three players made the final four in Seoul last week, with Alexandrova besting Ostapenko to win her second title of the season. The biggest questions surround Ostapenko and Raducanu, who both appeared to pick up injuries in their last matches.
